1. Choose correct alternative for each of the following questions(1) To draw graph of 4x + 5y = 19, Find y when x = 1.

Answer»

I don't know the answer

4(1) +5y=194+5y=195y=19-45y=15y=15/5y=5

for x =1,4x + 5y = 194(1) + 5y = 194 + 5y = 195y = 19-45y = 15y = 15/5y = 3

4x+5y=194×1+5y=194+5y=195y=19-45y=15y=15/5y=3y is 3 answer

4x+5y=19 , x = 14×1 +5y=19 4 +5y=195y=19_4 =155y =15 y= 15/5 =3y=3
